Subject: [PATCH v4 12/17] stk1160: Set the vb2_queue lock before calling vb2_queue_init
Date: Fri, 15 Jun 2018 16:07:32 -0300	[thread overview]
Message-ID: <20180615190737.24139-13-ezequiel@collabora.com> (raw)
In-Reply-To: <20180615190737.24139-1-ezequiel@collabora.com>

The vb2_queue will soon be mandatory. The videobuf2 core
will throw a verbose warning if it's not set.

The stk1160 driver is setting the queue lock, but after
the vb2_queue_init call. Avoid the warning by setting
the lock before the queue initialization.
